Abstract

The invention relates to a sample taking device for obtaining an analyte sample. Said device comprises a supply pipe (30), a discharge pipe (40), and an analyte feeding chamber (13) that is fluidically connected between the supply pipe and the discharge pipe. The analyte feeding chamber has an opening (14) that is fitted with an analyte-permeable membrane (15) in order to allow the analyte to penetrate from a zone located outside the analyte feeding chamber into the analyte feeding chamber. The maximum area of the opening of the analyte feeding chamber is 400 times, preferably 100 times, and most preferably 50 to 80 times the minimum cross-sectional area of the discharge pipe. Said device makes it possible to reduce the delay between the time the analyte penetrates the membrane and the time the analyte is detected on the sensor.
